BMR Calculator (Basal Metabolic Rate) helps you estimate how many calories your body burns at rest. It represents the minimum amount of energy needed to keep your body functioning, including breathing and keeping your heart beating. Your BMR uses up about two-thirds of your daily calories. Knowing your BMR can help you create a more effective strategy for weight loss, allowing you to better keep your calorie count on track and better understand the effect exercise will have on your waistline. The BMR formula uses the variables of height, weight, age, and gender to calculate the Basal Metabolic Rate (BMR). This is more accurate than calculating calorie needs based on body weight alone.
